4C1JPG on satellites - 14-30 October 2011

Hi! I saw this on another mailing list, and haven't seen any mention of it anywhere else, so here goes.... Members of the "Radio Experimentadores de Occidente" radio club XE1TD will use the special Mexican call 4C1JPG during the 2011 Pan-American Games, currently taking place in Guadalajara. 4C1JPG ("Juegos Panamericanos Guadalajara", the Spanish translation of the event in that Mexican city) will be on 160m through 6m, as well as the satelltes through 30 October 2011. QSL cards will be available, as well as electronic confirmations in both LOTW and eQSL. More information about 4C1JPG, including the Mexican address of the 4C1JPG QSL manager, is available at: http://www.qrz.com/db/4C1JPG By the way, for those who work that station - or any Mexican station - and would like to send SASEs instead of including a US dollar bill or IRC with your QSL request, I have lots of Mexican postage stamps. Using SASEs works a lot better when trying to send something to a Mexican ham. Please e-mail me directly if you would like to get some stamps for QSLing. Good luck and 73!

Re: KickSat - a personal spacecraft of your own in space

I think it will be a great acheivement to successfully deploy sats this small and successfully receive data from them. I do, however, share your concerns regarding long term RF pollution. In the case of KickSat this would be mitigated by the short lifetime before re-entry of a few days and I understand the total bandwidth occupied by all the 10 milliwatt ChipSat transmitters will be under 100 kHz. KickSat is not a problem but you can see how this technology can be built on in the future. Low cost swarms of satellitess can be a valuable scientific tool. When it moves to the commercial arena we won't want it in our bands. The QB50 project https://www.qb50.eu/ is proposing to launch a swarm of 50 2U CubeSats, see AMSAT-UK Colloquium presentation at http://www.batc.tv/vod/QB50.flv QB50 will have a significant spectrum requirement. I note that in the USA the NTIA is considering a paper proposing 10 MHz of UHF spectrum for small satellites, see http://www.uk.amsat.org/2011/10/01/new-itu-service-for-cubesats-and-nanosat… Maybe that could be a solution to be problem ? Now you could say that if there's 10 MHz of spectrum between 400-2025 MHz going spare then the Amateur and Amateur Satellite Services could do with it ;-) The worrying thing is that some may consider our spectrum might fit the bill :-( 73 Trevor M5AKA

Russian geostationary satellite locator - with AO-7, AO-27 and FO-29
by Thomas Doyle 17 Oct '11

17 Oct '11

Andy Thomas G0SFJ posted a great web page for a vintage Russian geostationary satellite locator he was fortunate enough to buy at a flea market. I modified a program of mine to use the old school Russian IMMARSAT map as the basis for a polar projection satellite tracker. I am sure there are many other programs out there that do the same thing. Here are a few screen shots from yet another one. Even though the continents look a little funky the tracks actually came out quite close to SatPC32 tracks. It does take a little while to get used to the new look of the world. It is an equiangular projection so as you get farther away from the north pole things look larger. Who knew Australia was so large. http://www.tomdoyle.org/polarprojection/ http://sites.google.com/site/andythomasorg/Home/russian-geostationary http://www.bathurst1000.com.au/ Nothing to do with sats but it was a great race.

PACIFICON a Blast!
by Clint Bradford 17 Oct '11

17 Oct '11

PACIFICON in Santa Clara was a blast! Had a great time. Arrived Friday mid-day - in plenty of time to work AO-51 at 4:30PM PDT. Saturday, of course, was non-stop fun. Gordo emcee'd breakfast. I gave my satellite show twice - right before and right after lunch. Standing room only group of 56 attendees for the first show. About 47 for the second show. Then we worked passes outside: A0-27 "showed up" mid-pass for us at about 245PM PDT. Then AO-51 again for a GREAT pass at about 3:53PM PDT. The event didn't formally get a request in to work Commander Fossom aboard the ISS for his 3:06AM PDT pass on early Saturday morning ... He worked a Scout group FIVE MINUTES before streaking across Santa Clara - but his radios were already turned OFF for a while. BUT our group of several kids/Scouts/parents/hotel security staff enjoyed a video I had set up on Fossum's NASA career, and we all had a great time - albeit 3 o'clock in the morning ... (grin) The PACIFICON organization is a first-class group. They treat their speakers well ... offer all aspects of the hobby to their attendees ... and gave it all to us in a comfortable venue (Santa Clara Marriott). They will be hosting the NATIONAL ARRL Convention next year! The organizers gave me a table right inside the front door of the exhibition hall - couldn't have asked for better placement. AMSAT Symposium flyers and sat sheets and more were handed out to attendees. More will be posted on my Work-Sat YahooGroup later this week. Clint Bradford, K6LCS http://www.work-sat.com

Re: nanosatellite 2-way payload
by Andrew Glasbrenner 17 Oct '11

17 Oct '11

Just about any radio system used for comms with the command station could be adapted to a two-way mission. Mass and power budget are the limiting factors in most cases. Which nanosatellite did you help design? 73, Drew KO4MA AMSAT-NA VP Operations -----Original Message----- >From: Shashank Chintalagiri <shashank.chintalagiri(a)gmail.com> > >I'm curious, as someone who was involved in designing a nanosatellite. >What sort of payloads would be of interest to the amateur community? >When we started out, we did spend a fair bit of time looking for >payload, but most things to do with transponders seemed to be somewhat >unfeasible. >

Re: Jugnu (JNU)

Dinesh, thanks. For the record, the TLE we track with us that for object E. The frequency is 437.275 and TLE defined doppler. I'm in class right now, so can't look for the specific number. We heard it in 4 and 17 degree elevation passes, so when it is on, signal strength is probably not an issue. Our payload turns on whenever we command it to, and downlink is initiated from the ground. That is on a separate frequency, though, and we aren't doing it just yet while we try to understand the power situation.
